RAIL.

Specification of Letters Patent.

Patented 1, 1921.

Application filed September 16, 1919. Serial No. 324,060.

.will enable others skilled in the art to which it appertains to make and use the same.

This lnvention relates to an improved railroad rail and the principal object of the invention is to provide a rail having a renewable tread for the head of the rail, thereby permitting longer use of the rail since when the tread is worn it can be removed and a new tread put in place.

Another object of the invention is to so construct this removable tread that it may be either welded to the body of the rail or rolled into engagement with the body. This permits the body portion of the rail to be formed of a less expensive material than the tread portion which receives the wear and further assures a well constructed rail since the body portion and the renewable tread may be hardened the desired amount. It has been found in rail construction that very often the body portion or the head will not have the proper hardness or toughness, this being .due to the fact that the web and base portion tend to cool more quickly than the head.

Another object of the invention is to so construct this improved rail that the worn out tread may be removed and a new tread put in place and welded to the head without the necessity of removing the rail from the track ties, thereby saving a great deal of time and trouble.

This improved rail is illustrated in the accompanying drawing, wherein there is disclosed a vertical sectional view through the rail.

This improved rail is provided with a base 10 and a web 11 which supports the head 12. This resembles an ordinary rail, except that the head will not be quite as thickas an ordinary rail and further the uppefcorner portion will not be rounded as is ordinarily the case. This body portion of the rail will be formed of iron or a cheap grade of steel which will however have sufiicient strength to withstand the strain of a train passing over the rail without any danger of the rail breaking. The tread 13 is formed of a strip of very high grade steel which extends longitudinally of the rail and completely covers the head 12. This tread 13 is of suflicient thickness to make up the usual height of rail head when in place upon the head 12 and may be connected therewith either by welding or the tread may be rolled upon the head while the head and tread are still hot. The rail may be supplied by manufacturers with the renewable tread in place and additional treads supplied so that when the treads have worn through or have worn so far that it is considered advisable to renew them, the old treads may be renewed in any suitable manner as by grinding, and the new treads put in place and secured by electric welding thus making it unnecessary to remove the rails from the ties. This saves an expensive operation and further makes it unnecessary to remove the street paving or road bed. very eflicient and practical rail has thus been produced. It should be noted that in constructing these rails old rails of the ordinary type may be used by grinding the upper face of a worn rail to the proper thickness and then welding. Also if desired the treads of rails already in use and of an ordinary construction may be ground down with the rails in place upon the ties and tread strips then welded in place. It will thus be seen that it will not be necessary to tear up the old rails of a track already in use in order to provide the improved construction. It has been stated that in applying the tread to an old rail it will 'be welded to it but it is to be understood that if desired this may be done either by electric welding or by heating both the rail and the tread strip and connecting the same'in the heated state.

What is claimed is:

A rail having a surfacing cap of greater resistance to wear than the body of the rail itself, said cap being substantially of the same width as the tread portion of the rail with the base of the cap substantially parallel with the base of the rail and the upper surface of the cap, whereby the cap is re versible for application to the rail, and said cap being applicable to the rail and rolled thereon while the rail and cap are at a welding temperature.

In testimony whereof I' aifix my signature in presence of two witnesses.
